Four dialogues and metalogues about the nature of science

We analyse and explore, in the form of dialogues and metalogues questions about the dialogic nature of beliefs and students belief talk about the nature of science and scientific knowledge. Following recent advances in discursive psychology, this study focuses not on students' claims but on the discursive resources and dialogical practices that support the particular claims they make. We argue that students' discourse is better understood as a textual bricolage that is sensitive to conversational context, common sense, interpretive repertoires, and textual resources available in the conversational situation. Our text is reflexive as it embodies the discursive construction of knowledge and undercuts any claims to authoritative knowledge. The very conception of “belief” is itself an expression or construction from within the mundane idiom.... We learn to use “belief” in conditions when the “objective facts” are unknown or problematic and we want to indicate the tenuous character of our claim.... The notion of “real world” or “objective reality” is embedded in an extensive, pervasive language game which includes as an intelligible move or possibility the use of the very concept of “belief” itself.

The course as token: A construction of/by networks

In actor-network theory (ANT) the movement from the instability of science-in-the-making to the relative stability of ready-made-science is followed by tracing the path of a token or focal actor (either human or non-human) as it both constructs a network and is simultaneously transformed by the developing network. Within science education, a new course can be seen to be a token. It undergoes various transformations as it simultaneously changes those who encounter it (teachers, students, and interested actors beyond the school) and is changed by those same actors. This paper describes the way a new applied physics course introduced in British Columbia as part of a program in applied academics can be seen to construct different networks in different contexts and, in the process, to take on significantly different characteristics. Data are collected from interviews and observations in two different settings characterized in part by differences in the types of partnerships developed with industry, labour, and post-secondary groups. The success of the applied physics course in challenging traditional forms of school physics is seen to rely on the size and strength of the network in which it is imbedded.     

Will Undergraduate Students Play Games to Learn How to Conduct Library Research?

This exploratory study examines whether undergraduate students will play games to learn how to conduct library research. Results indicate that students will play games that are an integral component of the course curriculum and enable them to accomplish overall course goals at the same time they learn about library research.     

Aid effectiveness in education: Why it matters

This article introduces the special issue of Prospects on “Aid effectiveness in education”. It brings together case studies of attempts in several very different contexts to improve the effectiveness of the use of aid in the education sector. By drawing on the historical evolution of the new paradigm over the last 20 years, the authors make the case for a closer focus on aid’s effectiveness in education, as well as the need to reform the aid effectiveness architecture. In particular, they identify two major obstacles that need to be overcome to improve aid’s effectiveness in education: the lack of sufficient institutional and staff incentives for coordinated and harmonized behaviour; and factors that lead to risk-aversion and discourage innovation in delivering aid effectively.     

Repeated reports for child maltreatment among intimate partner violence victims: Findings from the National Survey of Child and Adolescent Well-Being

ObjectivesTo determine the prevalence of intimate partner violence (defined as any physical violence during the last 12 months or previously) among mothers who maltreat their children, and to examine whether mothers’ experiences of intimate partner violence (IPV) are associated with repeated reports (rereports) of children to Child Protective Services (CPS) during the following 18 months.MethodsData for the analyses were from the National Survey of Child and Adolescent Well-Being (NSCAW), a national probability study of children investigated for child maltreatment. The sample of 5,501 children (ages 0–14) was randomly selected from the families who entered the US child welfare system between October 1999 and December 2000. The analysis sample was restricted to 1,236 families in which caregivers were: (1) the alleged perpetrators of the child maltreatment at baseline (independently of substantiation status) and (2) the biological mothers (n = 1,212 or 98.6%), adoptive mothers (n = 17 or 1%), or stepmothers (n = 7 or 0.3%) of children not placed in out-of-home care.ResultsChildren of mothers physically abused by an intimate partner during the last 12 months or previously at the intake interview (44%) were twice as likely as children of mothers who had not experienced such violence to be rereported to CPS (29% vs. 14%, Odds Ratio = 2.0, 95% Confidence Interval = 1.1–3.4). Rereports occurred almost twice as quickly for children of mothers who experienced IPV compared to children of mothers who had not experienced IPV (Hazard Ratio = 1.9, 95% Confidence Interval = 1.1–3.0).ConclusionsThe higher risk and speedier rereports of child maltreatment associated with intimate partner violence highlights the need for universal assessment and provision of services for IPV among families that are investigated by CPS.     

Student teachers' entry perceptions about teaching primary science: Does a first degree make a difference?

It is problematic whether primary teachers benefit by completing a first degree especially when the teaching of specific subjects, here science, is the focus of attention. This study reports the comparative results of interviewing thirteen Canadian and ten Australian student teachers, both about to commence their Bachelor of Education. The Canadian students had completed an initial degree while nine of the Australian students were school leavers. The interviews, which explored views about teaching primary science, were analysed with this factor in mind. Student teacher perceptions reported include: how to recognise a “good” primary science teacher; perceptions of self as a “good” primary science teacher; expectations of how the teacher education program could assist their science teaching; and whether (for the Canadian students) the initial degree will help in becoming a primary science teacher. Analysis of the interviews suggests possible influences a first degree (among other factors) may have on perceptions related to primary science teaching and raises questions about what is the best general approach for preparing primary teachers to teach science effectivly.     

What has happened to intuition in science education?

Intuition was one of the four key themes for science education that emerged from the Woods Hole Conference in 1957. Despite the considerable influence of this conference on a generation of curriculum projects the intuition theme was almost completely ignored. Recent studies of intuition, including an analysis of Nobel laureates' views of scientific intuition, are considered. This enables several conceptions of the nature and role of intuition in science to be defined, and its importance to be assessed. The assumption that it is also important in science education is examined by considering conditions in science teaching and learning that may encourage intuitive thinking in the light of current research developments that could lead to a new agenda for school science.

Registered nurses' constructed meaning of concepts of solution and their use in clinical practice

Since the introduction of nursing into tertiary institutions in Australia in 1975, there has been increasing interest in the teaching of physical science to nurses. Various courses in physical science for nurse students have been developed. They vary in length and content but there is agreement that concepts taught should be closely related to nursing applications. The choice of relevant concepts tends to be made by individual curriculum developers. This paper reports an examination of the use of physical science concepts and their relevance from the perspective of registered nurses practising in general ward areas. Inherent in this study is the premise that for registered nurses to have ideas of the physical science underlying their practice they must have constructed meaning first for these concepts. Specific chemical concepts related to solutions are discussed in these terms. Specializations: phenomenology, thinking, caring, euthanasia and palliative care, curriculum development for nurses. Specializations: thinking, science curricula for nurses, isotope geochemistry, mass spectrometry.
